San Francisco Giants pitcher Jose Mijares poses in his World Baseball Classic jersey that he will wear when he represents Venezuela. The Giants took part in photo day at spring training Wednesday, Feb. 20, 2013, in Scottsdale, Ariz.

Scottsdale, Ariz. -- Left-handed reliever Javier Lopez already had decided to skip the World Baseball Classic and informed the Puerto Rican team. His little accident on the field Tuesday might have kept him out anyway.

Manager Bruce Bochy said he expects Lopez to miss three or four days as the bruise on his pitching hand heals.

A day after a throw from Madison Bumgarner hit Lopez on the back of the hand, the impression of the baseball's seams remains clearly visible.

Lopez explained what happened Wednesday. He and Bumgarner were playing catch in the outfield at Scottsdale Stadium when Lopez crouched like a catcher and Bumgarner threw a "nasty pitch."

"It was a split-change-cutter combo," Lopez joked. "It had a little bit of everything."

Wet day: The rain that hit Arizona on Wednesday morning would have been enough to wash out a regular-season game, but the Giants worked out indoors.

Pitchers who were scheduled to throw live batting practice on the two full fields instead threw off the four mounds in the Scottsdale Stadium batting cages. Hitters stood at the plates but did not swing. Other hitters went to the cages at the team's minor-league complex at Indian School Park.

Tim Lincecum still has not thrown to hitters, with the Cactus League beginning Saturday, but Bochy said he will not change the exhibition rotation, which he hasn't announced besides Vogelsong starting the opener against the Angels.

Um, who? Shane Loux, who pitched in 19 games for the Giants last year, is not a household name. In fact, he was not mentioned by name in an offseason wire story reporting that the fan in St. Louis who was arrested for pointing a laser at Loux during a game had been sentenced to probation.

"The things I'm known for most are giving up the longest home run in Texas Rangers history to Josh Hamilton and having a laser pointed at me," Loux said. "You've got to be known for something, right?"
